Description

The smoothnose wedgefish is a wedgefish (Rhinidae) from shallow coastal and estuarine water of the Indo-West Pacific. The species can grow to about 3 metres and has a strikingly mixed build: a flattened, wedge-shaped front with wing-like pectoral fins as in a ray, but a powerful, shark-like tail section with large fins. As a bottom-dweller it searches over sand and mud for crabs, lobsters, molluscs and bottom fish, which it crushes with flat jaw plates. It lacks a venomous spine and is harmless to humans; through fishing the species is strongly endangered.
